The present invention is a medical implant or device fabricated, in any manner, from a niobium (Nb)—titanium (Ti)—zirconium (Zr)—Molybdenum (Mo) alloy (Nb-TZM alloy). The implant or device has components at least partially fabricated from a metal alloy comprising a) between about 29 and 70 weight percent Nb; b) between about 10 and 46 weight percent Zr; c) between about 3 and 15 weight percent Mo; and a balance of titanium. The inventive alloy provides for a uniform beta structure which is corrosion resistant, and can be readily processed to develop high-strength and low-modulus, with the ability for conversion oxidation or nitridization surface hardening of the medical implant or device.
The present invention relates to niobium alloys suitable for use in the construction of dental and other medical implants, and devices. More specifically, this invention relates to a bio-compatible, corrosion-resistant niobium-based NbTiZrMo alloy for use in medical device applications which can be cold-worked to a high level of strength and flexibility for improving performance of orthodontic, endodontic, dental, orthopaedic, cardiovascular, and other medical implants and devices.
